Pouring container for storing pourable foodstuffs

Abstract

A container for pourable foodstuffs has a base, a side wall connected to the base and surrounding a storage chamber. An elastic cuff is connected with a first end to the side wall and has a second end with an opening. The cuff width decreases from first to second end along a longitudinal container axis. The elastic cuff can be pushed into and pulled out of the storage chamber. A sealing element shaped as a stopper can be inserted into the opening for closing the container and has a shank portion matched in shape and size to the opening such that sealing abutment of a shank portion surface against surfaces of the elastic cuff adjoining the cuff opening is established in a contact region of the shank portion when the stopper is inserted. The shank portion has an end with a thickened portion thicker than the contact region.

What is claimed is: 
     
       1. A pouring container ( 2 ) for storing pourable foodstuffs, the pouring container comprising:
 a base ( 4 ); 
 a side wall ( 6 ) connected to the base ( 4 ) and surrounding a storage chamber ( 18 ); 
 a cuff ( 10 ) composed of an elastic material, the cuff ( 19 ) comprising a first cuff end ( 12 ) connected to the side wall ( 6 ) and comprising a second cuff end ( 14 ) comprising an upper opening ( 8 ); 
 wherein a width of the cuff ( 10 ) decreases from the first cuff end ( 12 ) to the second cuff end ( 14 ) along a longitudinal axis ( 16 ) of the pouring container ( 2 ); 
 wherein the cuff ( 10 ), due to an elasticity of the elastic material, is configured to be pushed into and pulled back out of the storage chamber ( 18 ) along the longitudinal axis ( 16 ) of the pouring container ( 2 ); 
 a removable sealing element ( 20 ) configured to close the upper opening ( 8 ), wherein the removable sealing element ( 20 ) is shaped as a stopper configured to be inserted into the upper opening ( 8 ) and to be removed from the upper opening ( 8 ) to access the storage chamber ( 18 ); 
 wherein the removable sealing element ( 20 ) comprises a shank portion ( 32 ) having a shape and a size adapted to a shape and a size of the upper opening ( 8 ) such that a sealing abutment of a surface of the shank portion ( 32 ) against surfaces of the elastic material of the cuff ( 10 ) adjoining the upper opening ( 8 ) of the cuff ( 10 ) is established in a contact region of the shank portion when the stopper is inserted into the opening; 
 wherein the shank portion ( 32 ) comprises a first shank end facing the storage chamber ( 18 ) and the first shank end comprises a thickened portion that is thicker than the contact region of the shank portion; 
 wherein the removable sealing element ( 20 ) comprises an annular abutment ( 28 ) arranged at a second shank end of the shank portion ( 32 ) remote from the first shank end, wherein the annular abutment ( 28 ) prevents the removable sealing element ( 20 ) from being pushed through the upper opening ( 8 ) into the storage chamber ( 18 ), and wherein an outer circumferential rim of the annular abutment ( 28 ) contacts a surface of the cuff ( 10 ) at a spacing above the upper opening ( 8 ) and provides a stabilizing effect on the cuff ( 10 ) when the stopper is inserted in the upper opening ( 8 ). 
 
     
     
       2. The pouring container ( 2 ) according to  claim 1 , wherein the cuff ( 10 ) is connected by form fit to the side wall ( 6 ) of the pouring container ( 2 ). 
     
     
       3. The pouring container ( 2 ) according to  claim 1 , wherein the side wall and/or the base comprises recesses. 
     
     
       4. A pouring container ( 2 ) for storing pourable foodstuffs, the pouring container comprising:
 a base ( 4 ); 
 a side wall ( 6 ) connected to the base ( 4 ) and surrounding a storage chamber ( 18 ); 
 a cuff ( 10 ) composed of an elastic material, the cuff ( 19 ) comprising a first end ( 12 ) connected to the side wall ( 6 ) and comprising a second end ( 14 ) comprising an upper opening ( 8 ); 
 wherein a width of the cuff ( 10 ) decreases from the first end ( 12 ) to the second end ( 14 ) along a longitudinal axis ( 16 ) of the pouring container ( 2 ); 
 wherein the cuff ( 10 ), due to an elasticity of the elastic material, is configured to be pushed into and pulled back out of the storage chamber ( 18 ) along the longitudinal axis ( 16 ) of the pouring container ( 2 ); 
 a removable sealing element ( 20 ) configured to close the upper opening ( 8 ), wherein the removable sealing element ( 20 ) is shaped as a stopper configured to be inserted into the upper opening ( 8 ); 
 wherein the removable sealing element ( 20 ) comprises a shank portion ( 32 ) having a shape and a size adapted to a shape and a size of the upper opening ( 8 ) such that a sealing abutment of a surface of the shank portion ( 32 ) against surfaces of the elastic material of the cuff ( 10 ) adjoining the upper opening ( 8 ) of the cuff ( 10 ) is established in a contact region of the shank portion when the stopper is inserted into the opening; 
 wherein the shank portion ( 32 ) comprises an end facing the storage chamber ( 18 ) and the end comprises a thickened portion that is thicker than the contact region of the shank portion; 
 wherein the removable sealing element ( 20 ) is configured to be connected pressure-tightly to the cuff ( 10 ) and the cuff ( 10 ) is connected pressure-tightly to the side wall ( 6 ). 
 
     
     
       5. The pouring container ( 2 ) according to  claim 1 , wherein the pouring container ( 2 ) is comprised at least partially from a transparent material and the cuff ( 10 ) is comprised of a nontransparent material. 
     
     
       6. The pouring container ( 2 ) according to  claim 1 , wherein the cuff ( 10 ) comprises a reinforcing element ( 24 ) arranged at the first cuff end or the second cuff end. 
     
     
       7. The pouring container ( 2 ) according to  claim 1 , wherein the cuff ( 10 ) comprises a reinforcing element ( 24 ) arranged at the first cuff end and the second cuff end. 
     
     
       8. The pouring container ( 2 ) according to  claim 1 , wherein the cuff ( 10 ) comprises a bending point ( 26 ) in at least one region, wherein the bending point is formed by a cuff portion of reduced material thickness.
